“…The purpose of the watermark technique is to seamlessly hide the secret information inside the original message, making it more resistant to attacks. Watermarking approaches have been proposed by certain researchers in recent years [16]. Copyright protection, fingerprinting, authentication, copy control, tamper detection, and data hiding applications such as broadcast monitoring are all examples of digital watermarking applications.…”

Document tracking is considered crucial, particularly in schools that still use traditional administration methods. Meanwhile, the usage of forms in a school's office, such as the Budget Division, is still necessary and should not be removed as per the school’s current policy. As a result, the school should have a solid monitoring system in place to ensure that these forms are stable and reliable. The tracking system is a flexible solution that may be used as a collaboration and communication tool, and it can aid in the construction of a traceable process. The researcher investigates the school's key concerns regarding using paper-based forms, as well as how the school can track its progress and location. The usage of a watermarking algorithm and a QR code-based tracking system was explored in this study. In addition, the structure, applications, security, and strategies for using a QR code are discussed. Existing watermarking technology, according to relevant research, has the opportunity for development in terms of imperceptibility and endurance in the future.

“…In recent years, the QR code has also begun to be utilized in the field of digital watermarking. Literature [29] uses the QR code as a carrier and it is combined with two-level wavelet decomposition coefficients to embed watermark information, but its practicability is not strong. Literature [30] uses the three-level discrete wavelet transform coefficients of an image as the carrier, and embeds the QR code as watermark information in the carrier.…”

Digital watermarking technology is an effective method for copyright protection of digital information, such as images, documents, etc. In this paper, we propose a high capacity text image watermarking technique against printing and scanning processes. Firstly, this method obtains the invariant in the process of printing and scanning under the mathematical hypothesis model of print-scan transformation. Then based on the print-scan invariant, the Fourier descriptor is used to flip the trivial pixel points with high frequency information on the character boundary. Next, considering the resolution of the print-scan equipment and its influence on the print-scan invariant, a quadratic quantization function is proposed to embed watermark information of multiple bits for a single character. Finally, the QR code (Quick Response code) is researched, which has large information capacity, robust error correction ability and high decoding reliability. By using the QR code as the watermark information, we can reduce the impact of bit error rate during watermark extraction, and the robustness of the watermark information can be improved. The experimental results show that the proposed text watermarking algorithm has the advantages of anti-print scanning, anti-scaling, large capacity and good visual effects.

Digital Watermarking is a technology used for the copyright protection of digital applications. Watermarking is a concept of embedding a special symbol, watermark, into an electronic document so that a given piece of copyright information is permanently tied to the data. It is an effective way to protect copyright of multimedia data even after its transmission. In recent years image watermarking techniques are grown-up. So digital video watermarking is the next challenging task and it is becoming a current academic research topic. Digital watermarking is a process of embedding watermark into digital document, where watermark can be some binary data, a small image or a seed value. It can also be any arbitrary or serial number, possession identifier, information about the inventor, date etc, that would be inserted into the original digital products. Digital watermarking refers to embedding watermarks in a multimedia documents and files in order to protect them from illegal copying and identifying manipulations. We proposed a technique is Hybrid DWT, PCA and SVD method for digital video watermarking. In two parts a proposed method of watermarking is divided: watermark embedding and watermark extracting.
